LISTENING SAFELY

To protect your hearing, follow these
guidelines when you use headphones.
• Set the volume to the lowest set-
ting before you begin listening.
After you begin listening, adjust
the volume to a comfortable level.
• Do not listen at extremely high
volume levels. Extended high vol-
ume listening can lead to perma-
nent hearing loss.
• Once you set the volume, do not
increase it. Over time, your ears
adapt to the volume level, so a
volume level that does not cause
discomfort might still damage your
hearing.
